Y MEAN S FOR IMPREGNATIN'G HATCH SPLIRTS.

Application filed December 12, 1924. Serial No. 755,465.

This invention relates to match making machmes, and particularly to means for impregnating the match splints with a solution of material adapted to render them nonglowing when they, as completed matches, are ignited and the flame extinguished.

The principal object of my invention is the provision of means to diffuse a solution of impregnating material, in an economical and uniform manner, upon the surfaces of the individual splints during their progress with the splint carrier of a continuous match machine, in order that the splints can be thoroughly and rapidly dried without subjecting them to the action of a high temperature, yet the splints when dry shall be adequately impregnated with the material for the prevention of after-glow.

The invention, generally stated, comprises a spraying element mounted adjacent the path of the splint carrier and directed toward the travelling splints; means for supplying a solution of material, and also air under pressure, to the said element, and

2 means for moving the spraying element to and fro in a plane parallel, or substantially so, to the path of the splints during the travel of the carrier.

The invention also comprises means for concurrently operating the spraying element,

and the solution-supply means therefor, during the running of the match making ma-. chine, and for independently operating the said solution-supply means at a relatively slow speed while the machine is idle, the latter operation being to ensure the presence of the solution in the spraying element when the match making operation is resumed.

The'invention also comprises novel features of construction and combinations of parts which will be hereinafter described and claimed.

In the drawings- Figure 1 is a side elevation of splint impregnating mechanism embod ing my invention, showing a portion of t e splint carrier of a match. machine.

Fig. 2 is a plan of said mechanism, the carrier being indicated by dotted lines. 60 Fig. 3 is a vertical section, enlarged, of the spraying nozzle.

Fi 4 is a horizontal section through the oscil atory" shaft and its bearing box, as on the lined-4 of Fig. 1.

Fig. 5 is a perspective view of the'solution tank and adjuncts.

Fig. 6 is a similar view of the mechanism for supporting and operating the spraying nozzle.

Fig. 7 is a vertical section, enlarged, through the oscillatory shaft and the pipe connections therewith for the nozzle.

Referring to the drawings, 10 designates a portion of a splint carrier of a continuous match machine, which carrier comprises an endless chain of plates having rows of perforations into which the upper ends of splints (S) are forcibly inserted in consecutive rows, such splints thus being rigidly held and being transported in spaced relation throughout the match making cycle. Supported laterally of the carrier, and between the splint-inserting station and the drying unit which precedes the paraflin bath,

is a tank 11 containing a concentrated solu-' tion of a suitable anti-glowing impregnating material, such, for example, as ammonium phosphate; Partly rotatable'within the tank and its contents is a roll 12 fast on a shaft 13 having its bearings in boxes 14 on the end walls of the tank, the periphery of which roll is adapted in its rotation to carry thereon a film of the solution from the tank,

which film is delivered to an inclined trough 15 arranged in scraping contact at its upper end with the roll. This trough is preferably adjustably supported on a cross-rod 16 at one side of the tank, the trough, for this purpose, having perforated lugs 17 which are loosely fitted on the .rod and provided with set-screws 18.

which the solution supplied to the trough is delivered, which funnel communicates with a horizontal pipe 20 extending to a point below and substantially medially of the longitudinal path of the splint carrier. The inner end of the pipe has a downward discharge portion 21 terminating in a centrally perforated bearin ca 22 which; is seated on the upper recesse en of a vertical shaft 23 which is mounted to oscillate in an upri ht box 24 on the cross-beam 25 of a suita le supporting frame. Hence the pipe 20 communicates with the recess 26 of the shaft, and is also supported by the shaft. In the present instance the cap 22 is bolted to the upper end of an upright supporting bar 27,

Directly beneath the lower end ofthe trough is a funnel 19 1nto upper end of the nozzle.

the lower end of which is fastened to the sideof the box'24 for the shaft 23. Means for actuating this shaft, and also the roll shaft;

horizontally drilled into the recess 26 of the shaft and receives'one end of a pipe 29 which extends in a substantially radial direction-from the shaft 23 and is oscillated therewith. The pipe 29 slightly declines fromt-he shaft 23 and communicates with an upright nozzle 30 to which is delivered the solution supplied to the recess 26 by the depending pipe portion 21.

Below and parallel with the pipe 29 is a similar pipe 31, one end of which enters a hole in the projection 28 and communicates with a radial port 32 in the shaft 23. The opposite end of the pipe 31 enters the'nozzle 30 at a point below the pipe 29, and the port 32 of the shaft has fixed therein a flex ible pipe or hose connection 33 which leads to a suitable source of compressed air supply. 1 Hence air under pressure is supplied to the nozzle, the amount thereof being regulated by an ordinary control valve in the air line.

The nozzle, in its preferred form, comprises an integral body portion axially drilled from its upper end to a point short of its lower end to provide an upper chamber 34 having an elongated constricted lower portion 35. The nozzle is radially drilled to provide inlets for the pipes 29, 31, to the lower ends of the upper chamber 34 and its constricted, portion 35, respectively, and, therefore, when the apparatus isin operation air under pressure enters such constricted portion .and issues through the open The air passing across the inlet for the pipe 29 effects the flow of the solution to the upper chamber of the nozzle and by contact reduces the liquid to a fine spray or mist and projects it in that condition from the mouth of the nozzle and toward the splint bearing face of the carrler.

It is to be noted that the nozzle is an integral element devoid of movable or adjustable parts, and that the amount of the solution ejected is not controlled by varying the size of the inlets to the nozzle, but by the amount of the solution that is delivered thereto.

The shaft 23 is oscillated in a horizontal arc, and therefore the pipes 29, 31 and the nozzle 30 are correspondingly actuated. The sweep of the nozzle is in a plane parallel, or substantially so, to the path of the splints, throughout the width of the carrier, and, consequently, the spray or mist of impregnating solution is effectually discharged against and amongst the progress ing rows of splints borne by the carrier.

The quantity of the solution thus diffused upon and throughout the surfaces of the individual splints is small, yet it is ample to insure adequate impregnation for the prevention of after-glow.

U The particular means herein illustrated for rotating the shaft, 13, of the feed roll for the tank containing the impregnating solution, comprises two spaced-apart sprock t wheels 36, 37 loose 'on' said shaft, and a ratchet wheel 38 fast on the shaft in the space between the sprocket wheels. Each of the sprocket wheels bears a laterally-disposed pawl, 39, in engagement with the teeth of the ratchet wheel, and consequently when either of the sprocket wheels is rotated the motion thereof is transmitted through the rotating pawl to the ratchet wheel and the shaft 13. About the ,sprocket wheel 36 is a sprocket chain, 40, which is actuated from a continuously driven elementof the match machine in a manner to rotate the shaft 13 and its roll 12 at a normal working speed during the match making operation. Engaging the sprocket wheel 37 is a secondary chain, 41, which is continuously driven at a relatively slow speed by the usual auxiliary drive of the match machine, which I drive is in operation when the match machine is idle. Hence during the idle period the continuously rotating sprocket wheel 37 and its pawl impart a slow motion to the ratchet wheel and the shaft 13; the purpose of which motion, is to ensure the presence of solution in the nozzle when the operation of the match machine is resumed.

The oscillatory shaft 23 is actuated'concurrently with the roll shaft 13 during the operation of the match machine, and as a simple and eflicient means to this end, the sprocket chain 40 is arranged to pass from the sprocket wheel 36 to and about a sprocket wheel 42 fast on the outerend of a horizontal shaft 43 having its bearings in a standard 44 on a cross-beam 45 of the supporting frame. shaft 43 is a crank disk 46 which is operatively'connected by means of a rod 47 to a crank arm 48 on the foot of the vertical shaft 23, thereby effecting the oscillation of the vertical shaft to swing the nozzle to and fro beneath the travelling splints, as previously described. The ends of the rod 47 are preferably connected with the crank disk 46 and the crank arm 48 by means of ball and socket joints 49, 50, respectively, the joint connection with the crank arm being adjustable toward and from the Vertical shaft, 23, in order to vary the extent of the stroke of the nozzle, as desired. In the present instance, the crank arm 48 is longitudinally slotted, as at 51, ,to receive the threaded shank 52 of the adjacent ball member of the joint 50, and the shank isprovided with a clamp nut 53 which can be screwed hard against the under side of the crank-arm to secure the ball member in a predetermined position of adjustment lengthwise of the slot.

It is to be understood that my invention is not limited tothe particular construction and arrangement herein disclosed, as the mechanism may be modified within the principle of the invention and the scope of the appended claims.
